Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is mainly used in a septic tank which is an example of a water treatment apparatus, and for example, a liquid transfer used for transferring sewage (liquid) from an anaerobic filter bed tank to a contact aeration tank, a carrier fluidized bed, a biological filtration tank, etc. Relates to the device.
[0002]
[Prior art]
Conventionally, the liquid transfer device is preferably a device capable of intermittently transferring a constant amount. For example, a pumping device shown in FIG. 2 of Japanese Patent No. 2559177 is raised. This is because a non-return valve that opens on the inflow side but closes on the outflow side is provided on the bottom surface of the sealed container disposed so as to be immersed under the liquid level. A communicating air supply pipe is provided. A discharge pipe extending from the upper surface to the vicinity of the bottom surface is inserted into the sealed container, and one end of a U-shaped tube that is curved in a U-shape rising upward is formed in the middle of the discharge pipe. It is attached. The other end of the U-shaped tube opens into the sealed container at substantially the same height as the attachment portion of the one end to the discharge tube. Since the sealed container is submerged below the liquid level in this way, the check valve is opened by the pressure of the liquid and flows into the sealed container. However, the sealed container is sealed by the pressure of the pressurized air sent from the air supply pipe. The liquid level in the container is pushed down, and if the air pressure is higher than the balance between the air pressure and the pressed liquid level, the check valve is immediately closed by the pressure and the liquid flows into the discharge pipe. And it is discharged from now on. However, when the liquid level becomes lower than the lower end of the U-shaped tube due to the discharge of the liquid, the pressurized air flows directly into the discharge pipe and the pressurized air flows out from the discharge pipe. The pressure inside falls. Then, since the liquid pressure outside the sealed container is applied to the closed check valve, the check valve opens, the liquid outside the sealed container flows into the sealed container, and the liquid level inside the sealed container is the U-shaped tube. When reaching the upper end, the liquid flows into the U-shaped tube and seals with water, the discharge of air pressure stops, and the liquid in the sealed container is discharged in the same manner as described above.
[0003]
[Problems to be solved by the invention]
According to the above configuration, since it is necessary to secure a space for providing the U-shaped tube in the sealed container, there is not only inconvenience that the sealed container becomes large, but also when used in a septic tank, it is used for a long time. Along with this, sludge accumulated in the U-shaped tube, and the effective flow diameter of the U-shaped tube was reduced. In particular, as the time during which purification treatment is not performed increases, sludge accumulates at the bottom of the U-shaped tube, and the inside of the U-shaped tube may be clogged with sludge. Incidentally, it is conceivable to periodically remove the sludge by cleaning the inside of the U-shaped tube, but it is not only troublesome to clean, but is difficult to clean because the tube is U-shaped. Therefore, a special cleaning operation using a pressure pump or the like is required for the U-shaped tube, and the cleaning operation itself is very troublesome and there is room for improvement.
[0004]
In view of the situation described above, the present invention intends to solve a liquid that can suppress an increase in size and can perform a quantitative transfer of the liquid satisfactorily over a long period of time while eliminating a cleaning operation. It is in providing a transfer device for a vehicle.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the liquid transfer device of the present invention is disposed in the liquid stored in the storage unit, and is a sealed container for taking the liquid into the inside through a lower intake port, and the taking-in A check valve that opens and closes the opening, the check valve being opened by hydraulic pressure outside the sealed container, an air supply pipe for supplying pressurized air supplied from an air supply device into the sealed container, A pumping pipe arranged in a state where the transfer start end side is inserted to the lower part of the sealed container in order to transfer the liquid taken into the sealed container by air pressure from the air supply pipe to a specific location, and the sealed An auxiliary pipe having one end connected to the upper part of the pumping pipe in the container and the other end connected to the lower part of the sealed container is provided, and the liquid in the sealed container is taken in from the upper part of the sealed container and the auxiliary Feed the lower opening of the tube It is characterized in that arranged in a state in which the bottomed cylindrical storage amount adjusting tube was inserted from the lower end of the auxiliary tube inside it to the top with an inner diameter larger than the outer diameter of the auxiliary tube in order.
First, since the sealed container is submerged below the liquid level, the check valve is opened by the pressure of the liquid and flows into the sealed container. Then, when the liquid level of the liquid flowing into the sealed container becomes the same as the upper end surface of the storage volume adjusting pipe, the liquid flows into the storage volume adjusting pipe, and the flowed liquid flows into the auxiliary pipe from its lower end. By doing so, the lower opening part of an auxiliary pipe is closed with a liquid, and the inside of a sealed container is water-sealed. Since there is no escape space for the pressurized air sent from the air supply pipe into the sealed container from this point, the check valve is closed and the pressure in the sealed container increases. After the check valve is closed, the liquid moves into the auxiliary pipe, and the liquid level in the sealed container is pushed down by the air pressure from the time when the water level of the sealed container becomes the same at any position. Liquid flows into the pumping pipe through its lower end and auxiliary pipe and is discharged from the pumping pipe. However, when the liquid level in the sealed container becomes lower than the lower end of the auxiliary pipe due to the discharge of the liquid, pressurized air flows into the pumping pipe from the auxiliary pipe via the storage amount adjusting pipe, and the pressurized pressure is supplied from the pumping pipe. Since air flows out, the pressure in the sealed container decreases. Then, since the liquid pressure outside the sealed container is applied to the closed check valve, the check valve opens and the liquid outside the sealed container flows into the sealed container, and the liquid level in the sealed container is used for adjusting the storage amount. When reaching the upper end of the pipe, the liquid flows into the storage volume adjusting pipe and the auxiliary pipe, thereby sealing the inside of the sealed container as described above, and discharging the liquid in the sealed container as described above. Is called. By repeating this, the liquid can be transferred quantitatively intermittently. In addition, when the purification process has been delayed for a long time, that is, when the water level in the reservoir is at a position lower than the upper end of the reservoir volume adjusting pipe for a long time, sludge settles at the bottom of the reservoir volume adjusting pipe. Even if sediment is present, the purification process is resumed and the liquid level of the liquid flowing into the sealed container as described above becomes the same as the upper end surface of the storage volume adjusting tube. The impact generated when the liquid falls to the bottom of the storage adjustment pipe with a drop in the upper and lower dimensions of the pipe causes an agitating action at the bottom of the storage adjustment pipe to eliminate the precipitate. have.
As described above, the liquid in the airtight container is made to flow into the storage amount adjusting pipe from the upper part and from the lower end of the auxiliary pipe to the upper part, and is transferred to a predetermined location via the pumping pipe. Therefore, it is possible to suppress the enlargement of the entire apparatus in the horizontal direction as much as possible as compared with a conventional apparatus using a U-shaped tube. Moreover, the transfer amount of the liquid to be transferred at one time can be changed by simply replacing the storage amount adjusting tube with a storage amount adjusting tube having a different diameter or vertical dimension. In addition, if the storage volume adjustment pipe is configured to be movable in the vertical direction, it can be installed simply by moving the storage volume adjustment pipe in the vertical direction when installing the device according to the lowest liquid level in the storage section. The error can be easily eliminated.
[0006]
By forming an opening for communicating with the outside at the lower end of the storage amount adjusting pipe and providing a detachable lid that closes the opening, the lid can be opened and cleaned easily. If the storage amount adjusting pipe is configured to be removable, the cleaning operation can be further facilitated by removing the storage amount adjusting pipe.
[0007]
By providing an adjusting means capable of adjusting the position of the upper end of the storage amount adjusting pipe, even if the water level falls below a predetermined water level, the upper end of the storage amount adjusting pipe is adjusted to the changed water level. By adjusting the position downward, the liquid can be quantitatively transferred.
[0008]
The adjustment means comprises a drive device for forcibly moving the storage amount adjustment pipe in the vertical direction, and provided with a storage level detection means for detecting that the storage level of the storage section has dropped below a predetermined level, Drive control means is provided for driving the drive device so as to move the storage amount adjusting pipe in the vertical direction in accordance with a detection signal from the storage level detection means.
Even when the storage level of the storage unit fluctuates, the storage level detecting means detects that the storage level has fallen below a predetermined level, and a drive signal is sent from the drive control means to the drive device according to the detection signal. It is possible to output and move the storage amount adjusting pipe in the vertical direction.

[0015]
The operation of the liquid transfer device 1 will be briefly described. First, since the sealed container 7 is submerged below the liquid level, the sewage flows into the sealed container 7 by opening the check valve 8 with the pressure of the sealed container 7. To do. Then, as shown in FIG. 3A, the sewage in the sealed container 7 is stored from the time when the level of the sewage flowing into the sealed container 7 becomes the same as the upper end surface 12C of the storage amount adjusting pipe 12. By sequentially flowing into the volume adjusting pipe 12, the sewage flowing into the bottom of the storage volume adjusting pipe 12 is generated in the bottom of the storage volume adjusting pipe 12 and the lower end of the sewage flows into the auxiliary pipe 11. The lower opening 11K of the auxiliary pipe 11 that flows in from the pipe and communicates with the pumping pipe 10 is sealed with water. Since there is no escape space for the pressurized air sent from the air supply pipe 9 into the sealed container 7 from this point, the check valve 8 is closed and the pressure in the sealed container 7 increases. When the check valve 8 is closed, the sewage moves to the inside of the auxiliary pipe 11, and as shown in FIG. 3B, the water level in the sealed container 7 becomes the same at any position. (The volume of sewage flowing into the two pipes 11 and 12 when the sewage enters from the lower end to the upper end of the auxiliary pipe 11 when the check valve 8 is closed and sealed with water, that is, FIG. 3B. The liquid level in the sealed container 7 is pushed down by the air pressure from the time when the volume T is reduced by lowering the water level of the sealed container 7 from the two-dot chain line to the solid level shown in FIG. 10 flows through the lower end thereof and the auxiliary pipe 11 and is quantitatively transferred from the pumped water pipe 10 to the contact aeration tank 5 as described above (see FIG. 3C). However, if the liquid level in the sealed container 7 becomes lower than the lower end (the lower opening 11K) of the auxiliary pipe 11 as shown in FIG. Pressurized air flows from the auxiliary pipe 11 through the working pipe 12 and pressurized air supplied from the air supply pipe 9 flows out from the pumping pipe 10, so that the pressure in the sealed container 7 decreases. Then, since the liquid pressure outside the sealed container 7 is applied to the closed check valve 8, the check valve 8 is opened, and sewage outside the sealed container flows into the sealed container 7, and the liquid level inside the sealed container 7. When the water reaches the upper end of the storage amount adjustment pipe 12, the sewage flows into the storage amount adjustment pipe 12 and the auxiliary pipe 11, thereby sealing the lower end opening of the auxiliary pipe 11 as described above. Similarly, the quantitative transfer of the sewage in the sealed container 7 is intermittently performed.
